Rating Good stuff
Gets into places nothing else can reach. I do however wish the 360 tip had more holes around the perimeter.

Rating Easy To Apply, Works Great
I saw the Utube video of the guy fixing his rusty bottom of his car doors. It seemed simple so I ordered the stuff to do it. This products was easy to use. But the spray tip on the can, put the hose in the holes already on the inside of the car door and spray until the entire inside was coated. Some leaked out a hole and was easy to wipe up with a cloth danmp with mineral spirits. Great to be able to seal the car door up from the inside out! Highly Recommend!

Rating Used on Swing Set
I used this to coat the inside of a sing set because swing sets always rust and I needed to prevent that. It was easy to spray all over the inside of the metal tubing. I'm excited to have a coating on the inside of the swing set!

Rating Does exactly as described.
Does exactly what it said it would. Just be careful when applying it, as it'll drip out of the car. It's a solid product, when it dries it does not want to come up, so now I've got KBS cavity coating stuck on my driveway, at least I know it'll protect my Miata's rocker panels!

Rating Sealed Car Door
I watched the Utube video and sealed the inside of my car door that was rusting from the inside. It was a no brainer very easy to spray in with the wand. Good stuff.

Rating Better than other similar products
Similar type of product to FluidFilm, Amsoil MP HD or KanoKroil WeatherPruf. Its sort of a mix between wax and a little grease. This product seems more durable and its thinner so it creeps and penetrates better than the others in my experience. Expect to have to reapply after a while if you're using it as an undercoat or in an area directly blasted by water and road grime, it's best suited as protection for areas that are hard to get to like behind body panels and seams
